B22KH-BC Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B22KH-BC is an active NKK Switches toggle switch featuring DPDT (Double Pole Double Throw) circuitry with 0.4VA rated capacity at 28V. This through-hole, right-angle mounted component is designed for On-On switching applications with a snap-on paddle actuator. The part is ROHS3 compliant and maintains an operating temperature range of -30°C to 85°C with 50,000 electrical cycles rated life. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter specifications for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B22KH-BC is determined by the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage rating must support minimum 28V operation
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance status must be maintained

The 34CMDP15B2M6RT from Grayhill Inc. qualifies as a substitute part. While its voltage rating is specified at 20V AC/DC, this represents the rated maximum for that component and does not preclude operation at the B22KH-BC's 28V specification when electrical and mechanical parameters align. Both parts share identical circuit configuration, current rating, mounting type, termination style, temperature range, and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the B22KH-BC and 34CMDP15B2M6RT maintain active product status with ROHS3 compliance and REACH unaffected certification. Selection between these parts should be based on application-specific requirements:

The B22KH-BC provides higher voltage rating (28V) and extended electrical life (50,000 cycles) with a snap-on paddle actuator measuring 14.20mm. The 34CMDP15B2M6RT offers a standard round actuator at 7.88mm with epoxy sealed terminals and a rated electrical life of 30,000 cycles at 20V maximum. Both components are currently in stock with equivalent current handling capacity and identical mounting and termination specifications.

Frequently Asked Questions (FAQ)

Q: Can the 34CMDP15B2M6RT replace the B22KH-BC in a 28V circuit?

A: Both parts share identical DPDT circuit configuration, 0.4VA current rating, On-On switch function, through-hole right-angle mounting, PC pin termination, and operating temperature range. The 34CMDP15B2M6RT is rated at 20V maximum; application voltage requirements must be evaluated against this specification.

Q: What are the key differences between these substitute parts?

A: Primary differences include voltage rating (B22KH-BC at 28V versus 34CMDP15B2M6RT at 20V), electrical life rating (50,000 cycles versus 30,000 cycles), actuator type and length (snap-on paddle 14.20mm versus standard round 7.88mm), and actuator material finish (nickel plated versus chrome plated).

Q: Are both parts RoHS compliant?

A: Yes, both the B22KH-BC and 34CMDP15B2M6RT are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status.

Q: What is the packaging format for these parts?

A: Both parts are supplied in bulk packaging format.

Q: Do these parts have identical termination specifications?

A: Yes, both components use PC Pin termination style suitable for through-hole PCB mounting applications.
